GLASS-FURNACE.

SPECIFICATION forming part of Letters Patent No. 323,937, dated August 11, 1885.

Application filed March 13, 1895.

To all whom it TIY/CI/y concern:

Be it known that I, LUo HOUZE, of Meadville, inthe county of Crawford and State of Pennsylvania, have invented an Improved Glass-Furnace, of which the following is a specification.

The general object of my invention is to facilitate the use and lessen the cost of gas for heating purposes in glass-furnaces. Heretofore it has been manufactured in separate gas works at an unnecessary waste and expense of fuel; and my specialobject is to provide glass-furnaceswith means for converting the smoke, slack coal, or other fuel into gas by the melting-furnace itself. 7

Figure l of the drawings is a front eleva tion showing the fire-box, conductor, and connections. Fig. 2 is a transverse vertical section through the conductor and fire-box. Fig. 3 is a horizontal section through certain airfiues. Fig. 4 is a transverse vertical section through the melting-chamber and subjacent air-fiues.

In the drawings, A represents the meltingchamber of one side of a glass-furnace, the same being provided with the usual meltingpots A.

B is a fire-box having the hopper I), through which coal or other analogous fuel may be entered. The products of combustion pass up from this firebox through the hole 1) into the median flue of the conductor E; thence, by means of horizontally-partitioned chambers e e and the dampers e 6. they may be distributed at a greater or less elevation in the meltingchamber A and with respect to the meltingpots.

A represents an open space under a brickarch and on a brick foundation, preferably.

B is a trunk opening into said air-space and hanging in the middle of fire-chamber. At b it opens into a flue, B which leads to an air chamber, B From thence the air passes into side fines, 6 6 one on each side of the smoke-flue. a represents chimneys connecting with the melting-chamber and a common stack on the top of the apparatus. 7

O O are two air-fines, which run under the melting-chamber in a longitudinal direction and open at c 0 into the arched space below,

(No model.)

so as to receive therefrom a supply of air, which passes into the side flues, e c". From flue e and side flues, e" 6, issue products of combustion and hot air, which mix together as they enter the melting-chamber. This new supply of hot oxygen causes a complete combustion of the remaining carbon in said products, and thus utilizes a maximum of the caloric in the fuel.

Thus I make a cleaner gas and at much less expense than is now usual in glass-furnaces.

Having described my invention, what I claim to be new, and desire to protect by Letters Patent, is

1. In a glass-furnace, the combination, with the melting-chamber A and fire-box B, of the conductor E, having one median and two side flues opening near each other into the said melting-chamber, the median flue connecting with the fire-box and the side flues with an air-supply, as shown, whereby the products of combustion from the fire-box may receive an additional supply of oxygen as they enter the melting-chamber, for the purpose specified.

2. The combination, with the melting-cham her A and fire-box B, of the conductor E, having smoke-flue e and air-flues e 6, arranged side by side and discharging into the meltingchamber at the sametime, as and for the purpose specified.

3. In a glassfurnace, the combination, with the melting-chamber having melting-pots A and the fire-box B, of the conductor E, having partitioned chamber 6 and dampers e 6, whereby the products of combustion may be distributed, as set forth.

4. In a glass-furnace, the combinatiomwith the melting-chamber, of the trunk B, open at b, the flue B, and the fines e" e 6 arranged substantially as and for the purpose specified. 5. The combination, in a glassfurnacegvith the meltingchamber, of the tines O 0, running thereunder, and the flues c e in the conductor E, as and for the purpose described.
